Explanation: The Sahel region is located in Africa between the Sahara to the north and the Sudanian Savanna to the south.
The Sahel has a semi arid climate which is characterized by precipitation below potential evapotranspiration.
What this means is that the amount of water that would be evaporated and transpired by a specific crop or ecosystem is low. This region is prone to desertification or drought because of the low amount of water evaporated and transpirated in the region.
